The store sold four division one winning tickets in 2016, with prize money totalling close to $5.6 million.

Cannington local Sukh Grewal said he was among many who had waited in line for more than half an hour to buy a ticket from a store that had delivered big winners.

He said the wait would all be worth it because “I’m going to win tonight”.

He said there was a good vibe among those in the two snaking lines.

“Everybody is happy to wait. Everybody thinks they’re going to win,” he said.

Lotterywest spokeswoman Pina Compagnone said one in two West Australians will enter tonight’s draw, which is the equal largest prize on offer in national history.

“There are more than 500 Lotterywest stores who have been reporting busy periods, with interest set to peak this afternoon when close to 1200 tickets will be produced from lottery terminals each minute,” she said.

If one single ticket claims the prize it will be the biggest Lotto win ever in Australia, beating the $70m claimed in 2013 and 2016.
